www.pulsar.pl PSBOC351225 The shock protection circuit shall be performed with a particular care, i.e. the yellow and green wire coat of the power cable shall stick to one side of the ‘PE’ terminal. Using the PSU without a properly made and fully operational shock protection circuit is UNACCEPTABLE! It can cause a device failure or an electric shock. 4. Connect load/loads to proper output connectors of the power supply (positive pole is marked as +V, negative pole as -V) 5.

LED indication The PSU is equipped with 3 LEDs on the PCB board: - red LED (Fig.2, element 1) normal status (AC power): permanently illuminated. AC power absence is indicated by the AC diode going out. - green LED (Fig.2, element 2) indicates DC power at the PSU output. Under normal status the diode is permanently illuminated. In case of a short circuit or an overload, the diode is off. - green LED (Fig.

Overload or short circuit of the PSU module output In case of an overload or a short circuit at the PSU output, the output voltage is automatically cut off. The voltage is restored automatically after removing the failure (overload). 4.2. Battery-assisted operation. In case of a main power outage, the device is immediately switched into a battery-assisted operation. The PSU is equipped with the discharged battery disconnection system.
